I made these tile coasters the other day to give away as a raffle prize at a baby shower.
First I cut a piece of lace to fit the tile. Then I sprayed it with tacky glue. Next I put the lace down and spray painted red. Then I simply removed the lace and moved on to the next tile. finally I mod podged thin cork squares to the bottoms of each tile. It didn't turn out quite as nice as I had hoped, but they still turned out pretty neat.
